Pests in Gardens and Landscapes

Pest identification and confirmation—Oak
branch dieback

Unlike oak twig blight, which causes dead white or tan leaves in scattered patches throughout the canopy,
oak branch dieback generally occurs in a whole section of the tree while other parts of the plant appear
healthy. Oak twig blight is associated more with wet conditions; oak branch dieback is more prevalent
during and after periods of drought. Both diseases may become more prevalent when trees are stressed from
environmental conditions.
